Cryptanalysis: History & Applications

Cryptanalysis (from Greek kryptós 'hidden' and analýein 'to analyze') refers to the process of analyzing information systems in order to understand hidden aspects of the systems. Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown.
